M184V/I are not contraindications to continued treatment with 3TC or FTC because they increase susceptibility to AZT and TDF and are associated with clinically significant reductions in HIV-1 replication. M184V/I causes a 5-fold reduction in islatravir susceptibility of uncertain clinical significance. |

Consolidated analysis of RT mutations and their clinical implications for HIV drug resistance. This table groups information by mutation, showing affected drugs and their resistance scores, with detailed clinical commentary.
Clinical interpretation of RT mutations, including effects on drug activity and viral fitness, with linked drug-specific context.
| Mutation Type | Type | Mutation | SDRM | APOBEC | Affected Drugs | Max Impact | Clinical Implication |
|---|---|---|---|---|---|---|---|
| NNRTI_E138Q | NNRTI | E138Q | No | No | RPV (NNRTI) (20.0), DPV (NNRTI) (20.0), EFV (NNRTI) (10.0), ETR (NNRTI) (10.0), NVP (NNRTI) (10.0) | 20 | E138Q/G are non-polymorphic accessory mutations selected by ETR occasionally NVP and EFV. They cause low-level reductions in susceptibility to NVP, RPV, and ETR. |
| NNRTI_G190A | NNRTI | G190A | Yes | No | NVP (NNRTI) (60.0), EFV (NNRTI) (45.0), RPV (NNRTI) (15.0), DPV (NNRTI) (15.0), DOR (NNRTI) (10.0), and 3 more | 60 | G190A is a non-polymorphic mutation that causes high-level resistance to NVP and intermediate resistance to EFV. It does not significantly reduce susceptibility to RPV, ETR, or DOR. |
| NNRTI_V179D | NNRTI | V179D | No | No | EFV (NNRTI) (20.0), NVP (NNRTI) (20.0), RPV (NNRTI) (15.0), EFV (NNRTI) (10.0), ETR (NNRTI) (10.0), and 3 more | 20 | V179D/E are somewhat polymorphic accessory NNRTI-selected mutation. In combination with other NNRTI DRMs, they appear to contribute low-levels of reduced susceptibility to each of the NNRTIs. In particular, the combinations of K103R/V179D and V106I/V179D act synergistically to reduce NVP and EFV susceptibility. |
| NNRTI_Y181I | NNRTI | Y181I | Yes | No | ETR (NNRTI) (60.0), NVP (NNRTI) (60.0), RPV (NNRTI) (60.0), DPV (NNRTI) (60.0), EFV (NNRTI) (30.0), and 4 more | 60 | Y181I/V are 2-base pair non-polymorphic mutations selected by NVP and ETR. They cause high-level resistance to NVP, ETR, and RPV but not EFV. Their effects on DOR have not been well-characterized. |
| NRTI_D67N | NRTI | D67N | Yes | No | AZT (NRTI) (15.0), D4T (NRTI) (15.0), ABC (NRTI) (5.0), ABC (NRTI) (5.0), AZT (NRTI) (5.0), and 5 more | 15 | D67N is a non-polymorphic TAM associated with low-level resistance to AZT. |
| NRTI_L74I | NRTI | L74I | Yes | No | DDI (NRTI) (60.0), ABC (NRTI) (15.0), TDF (NRTI) (5.0) | 60 | L74V causes intermediate ABC resistance. L74I causes low-level ABC resistance. L74V increases AZT, TFV, and islatravir susceptibility. |
| NRTI_M41L | NRTI | M41L | Yes | No | AZT (NRTI) (15.0), D4T (NRTI) (15.0), ABC (NRTI) (10.0), ABC (NRTI) (10.0), AZT (NRTI) (10.0), and 11 more | 15 | M41L is a TAM that usually occurs with T215Y. In combination, M41L plus T215Y confer intermediate / high-level resistance to AZT and contribute to reduced ABC and TDF susceptibility. |
| NRTI_M184V | NRTI | M184V | Yes | No | FTC (NRTI) (60.0), 3TC (NRTI) (60.0), ABC (NRTI) (15.0), ABC (NRTI) (10.0), DDI (NRTI) (10.0), and 3 more | 60 | M184V/I cause high-level in vitro resistance to 3TC and FTC and low/intermediate resistance to ABC (3-fold reduced susceptibility). M184V/I are not contraindications to continued treatment with 3TC or FTC because they increase susceptibility to AZT and TDF and are associated with clinically significant reductions in HIV-1 replication. M184V/I causes a 5-fold reduction in islatravir susceptibility of uncertain clinical significance. |
| NRTI_T69D | NRTI | T69D | Yes | No | DDI (NRTI) (30.0), D4T (NRTI) (10.0) | 30 | T69D is a nonpolymorphic mutation selected by early NRTIs that does not appear to reduce AZT, ABC, or TDF susceptibility. |
| NRTI_T215F | NRTI | T215F | Yes | No | AZT (NRTI) (60.0), D4T (NRTI) (40.0), DDI (NRTI) (15.0), ABC (NRTI) (10.0), ABC (NRTI) (10.0), and 11 more | 60 | T215Y/F are TAMs that causes intermediate/high-level resistance to AZT and potentially low-level resistance to ABC and TDF. The presence of ≥2 TAMs appears to reduce islatravir susceptibility but the impact of individual TAMs is not known. |
| Other_K103R | Other | K103R | No | No | EFV (NNRTI) (20.0), NVP (NNRTI) (20.0), RPV (NNRTI) (15.0) | 20 | K103R is a polymorphic mutation that alone has no effect on NNRTI susceptibility. However, in combination with V179D, it reduces NVP and EFV susceptibility about 15-fold. |
